ROTARY PLOW.

7?) alive/1.0m it may concern:

in it known that l, llleivrox l. iilliPPY, a citizen of the United Slates. and a resident of Lander, in the county of Fremont and State of llyoniing, have invented a new and Improved Rotary Plow, ol' wl'iich the following is a full, clear, and exact (iv-scrip tion.

My invention relates to a tractor plow having pov v( *.r-tlri\'cn rotary plow means, and more particularly the invention of the present application relates to a motor plow structure embodying plowing aml pl m controlling means.

The prime object of the present invention is to prorhlc a rotary pine with rakingainl lowering means, and illl'illls .-sorialril there- With to positively act to give '1 ic nx a'cal movement to the plowing means when ion ering the same instead of relying); solely on the gravity of the said plowing means.

The nature of the invention and the ad" vantages of the structural features entering into the preferred. practical. embodiment thereof will more clearly appear as the (lescription proceeds.

Reference is to be had to the accompanying drawings forming a part of this specili cation in which similarieferencc characters indicate corresponding parts in all the views, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a longitudinal vertital section of a rotary tractor plow embodying my invention, the section. bcin taken. approxi mately at the center;

Fig. 2 is a detail front view showing the plow raising and lowering shaft and its actuating means;

In carrying out my invention in accnrrt ance with the illustrated (,Xi'llllplfi a tractor is provided with a frame 10 and snpcrstruc. ture 11. Mounted on the same is any approved motor 12 here conventionally shown. A main drive shaft 14 is driven from the engine shaft 13 through suitable intermediate connections, there being shown gear wheels 16 mounted on a shaft 17 and mesh ing with a gear wheel 15 on the engine shaft 13 and with a pinion 18 on ihe drive shaft 14. Positive drive connections arc established between the drive shaft. 1! and both the front and rear axles. As one ample of means for the purpose, I have Specification of Letters Patent.

Application filed July 6 1915-.

illustrated a 'lll."i3 )ll1l(:1'v 19 on the shaft l4 meshing; with a gear wheel 20 on a shaft 21. the Wheel E30 in turn meshing with a gear Wheel 15;? on lhc front axle tarrying the traction n'hccls El. For (ll-lying lhe rear axle the pinion l!) meshes also with a. gear wheel on a shaft 26, said Wheel 25 in turn meshing with a gear whcelli' fixed on the rear axle having traction wheels 29.

For shaming the front axle a steering post 3i has a wheel 35 ihereon and at its lower end has a worm 5K6 geared with a. worn'l wheel 37 on a. short shaft 38. The shaft 3; has :allilnlilc connection with axle *l. the nariicnim: steering moans forming m nail oi the prcsrni invention.

'ilnm ni pinning means comprises a v wii lrio plow in tin formof a reel desigmi n -raily hr the numeral 453 and havmgr i 'n-l... ll in a vertical r0ckahlitra ii'l hon at its rear end on like :irin: axle 11. To give rotary movement to the plow 4:? a drive connection is established hefiwccn said plow and the drive shat t 1- For the purpose in the illustrated construction gear wheels 4 are fixed on the plow at each call and are adapted to be driven from the drive shaft by a gear train 15 at cacli side of the machinc. One Wheel of each train is in mesh with a Wheel l4 and another in mesh with a gear wheel 46 on the drive shaf ,th ariangcment being duplieatell a ea h shlc of the machine. It will. be seen that the frame 47 carrying the r0- lary piow I "wing 'rnrtically through an iillgi i" .it t. i oi" n (ll-ire shaft 14 t ra sing; a l liWJOI'lP-Q the plmv. For raising ca plow 432 there is connected with the frame 47 at the front end, at the approximate center, a. cable 48 which runs over suitaljile guide sheaves 4.9 to a drum 5Q on a shaft 50 adapted to be manually turned by any suitable means as for example a known type of ratchet mechanism as illustrated, eonnm'isin; ratchet levers 51 tarrying pawls 5i? engaging at opposite sides of a. ratchet Win-cl 53 on the shaft 50. The numeral 5 inrlicatcs a latch lever having a latch 55 to engage hc ratchet wheel to hold ihe plo in a. given adjustment. In ur'tlcl. in cam-l a positive downward pressure on the plow frame 47 in lowering the low, 1 provide swinging pressure arms 56 hung at their upper ends as at 5? on a. suitable member of the frame or superstructure and carrying rollers 58 at the lower ends, there being one arm 56 at each side of the machine. The rollers 58 bear on inclines 59 on the frame 47 at each side and cables 60 connect with each arm near the lower ends as at 61 and wind on the ends of the shaft 50. The cables 48 and 60 wind reversely on the shaft.

-the arrangement bein such that as the shaft is operated to lower t e rotary plow .42, the cable 48 will be aid out while the cable 60 will be wound in thereby pressing the rollers 58 against the inclines '59 and thus positively depressing the plow. With the raising of the plow a reverse movement is given to the arms 56, since the cables 48 will be paid out permitting the inclines 59 to swing the arms outward y that they may not interfere with the raising of the plowl The plow 42 is provided on the outer ends of the arms and connecting the latter, with longitudinal plowing bars 42, the opposite edges of which are serrated whereby to readily enter and engage the ground and thoroughly break up the same. Said bars 42 are curved in cross section.

I wish to state in conclusion that although the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the mechanical details herein illustrated, since manifestly the same can be considerably varied without degarture from the spirit of the invention as efined in the appended claims.

Having thus described my invention, I claim as new, ters Patent:

1. The combination in a plow of a main frame, an auxiliary frame ivoted on the main frame to swing vertica 1y, a cable attached to the auxiliary frame, means to control said cable to exert'a lift on the said auxiliary frame or permit the same to lower, arms swingingly mounted on the main frame, inclines on the auxiliar frame against which the said arms are a apted to bear to exert a downward pressure on the said auxiliary frame, and means arms into engagement with said inclines when the auxiliary frame is being lowered.

2. The combination with a main frame, of an auxiliary frame mounted on the main frame to swing vertically, a plow on the auxiliary frame, means to exert a lifting action on the auxiliary frame or to permit the same to lower for raising or lowering the plow, swin ing arms on the main frame, iIlOlHlBS on .t e auxiliary frame against which said arms are adapted to bear and to swing said means to swing said arms to exerts ownward pressure against the said inclines.
